Density = Mass / Volume. So, if your volume stays the same, and there is a greater mass of air, then the density goes up.
If the mass of a fixed volume of air increases, the density of the air becomes more dense. Density is defined as mass divided by volume, so as the mass increases while the volume remains constant, the density increases.
If the volume of the air inside a balloon increases while the mass remains constant, the density of the air inside the balloon will decrease. This means that the air inside the balloon will become less dense.
If the mass of a fixed volume of air increases, it becomes denser. This means that there are more air molecules present in that volume, making the air more compact and heavier.
density is mass per unit volume so the less mass per cubic(what ever measure) the less buoyant.
force = mass * acceleration then mass and acceleration is inversly proportional. Actually mass is constant but when the speed increases the mass become less since acceleration and velocity is directly propotional thus acceleration increases too.....thx..with best regards..
The air is less dense.
resistance of only electrolytes and semiconductors decrease wid temp.This is so coz in these substance due to increase in temp, the no. of ions and electrolytes in conduction band increases .Thats why resistance decreases.
Warm air is less dense than cool air masses because of their density levels.
Materials become denser as they get colder, unless, like ice, some other molecular force makes them less dense. Solids are denser than liquids, which are denser than gases. The colder a solid is, the more dense it becomes because each molecule's energy, which helps it repel the others, is less.
No, it does not.
If the volume is tripled while the mass remains constant, the density of the object will decrease because density is mass divided by volume. This means that the object will become less dense and occupy more space.
Density is determined by the amount of mass in a given volume. Something is considered dense if it has a high mass for a given volume, while it is considered not very dense if it has a low mass for a given volume. Materials with tightly packed particles are usually dense, while materials with loosely arranged particles are less dense.
